To all/7071 0117 it "my concern.-

Be it known that I, PAUL OLsoN, citizen of the United. States, residing at Stc-ughton, in the county of Dane and State ol' Wisconsin, have invented certain new and useful Improvements in Building-Blocks, of which the following is a specification.

My invention relates to improvements in what may be styled building-l)loeks. its object is to promote air-circulation or ventilation within the wall built of the blocks, to increase the bonding action between the blocks, to render the joints water and air tight and .lirm and strong, also to secure ell'ective bonding er bracing action between. the outer and inner liloc'k-ct-lurses ol' the w. .ll to neutr.:.lize or compensate for any deliciency which might result from the presence of the air-circulating or ventilating airspaces provided in the wall.

To these ends said inventionconsists o'l' certain structinzd l'e..=.t11res of the blocks substantially .:.s hereinafter fully disclosed .nd specifically pointed out by the l...li1l.

In the acctmpnnying dr...wings, illllHl-lal ing the preferred embodiment of my invention, Figure 1 is a broken plan view slmwing .t fragmentary course of the blocks, .s in torming or erecting the w-.:.lls cf a'building. Fig. 2 is a like view showing a fractional superposed course of the blocks with the like lower course indicated in dotted lines. Fig. 2; is a detached perspective view, and Fig. 4 is a like view of blocks employed in erecting a wall -.i-,ccording to my invention.

In carrying out the invention I employ blocks (designated as] 2 3) for the (PUUHJII of the wall, and in doing this the blocks are laid from the base or ground up in two courses 4 5, parallel to each other and having an intervening space 6 therebetween of about one inch in cross-sectional area extending continuously along and within the plane of both the side and end Walls from top to bottom. The corner-walls 6' are each composed of blocks 3 as to its outer course, while its inner course is produced of blocks 2, and the intervening or lateral walls proper are constituted of blocks 1 both as to their outer and inner courses, said blocks all being arranged to break joints or having their joints alternatin The blocks 1 of both courses are practically rectangular at their ends with the intermediate portion of each-block oi the two courses produced with a vertical longitudinal recess A in its inner surface adapted to form the tortuous air-space 6 above noted, and each has in one end a vertical recess 7, and at its other end a verl ical tongue or extension 8, engaging mlrrespondingextensionsor tongues l) and recesses 10 of the blocks 3,respectively, ol' the outer course 5. The blocks 3 are each appnaxiinatoly right-angled in general outline with its end portion 11 having the relatively greater area and provided with the recess 10, lacing in a direction at right angles to that of its general length and the direction in which the other end of said block faces, and which end has the extension or tongue 9.

The blocks 2, two of which are arranged at diagonally opposite corners of the walls within the inner courses 4 thereof, have the larger end portion of one 0] each such two interlocking with the narrower or elongated end portion ol' the other, a shozlder 13 oi the latter abutting the inner lateral edge of the former, tlu'.s mutually bracing each other. The narrower or elongated portion ol each said two interlocking blocks extends from the end walls into the lateral or side walls and has also a shoulder 1-t engaging each of the :uljoining blocks 1'.-

It will be noted that the larger ends of the end blocks 2 are eqripped with recesses 15 16, respectively, which provide additional air-passages for t:.rther ventilation, especially the end walls; also, that the diagonally opposite end blocks 1 of the inner courses of the side or lateral walls are likewise provided with recesses 19 20, respectively, for the like purpose as aforesaid.

The superposed courses 17 18, both the innor and outer, of the side and end walls are laid practically in like manner as the aforesaid eo' 'rses, the same, however, breaking or alternating joints with the latter, as shown.

Series of building-blocks, forming the two opposed co rses, both for the lateral and end walls, and having three dill'erent strnetrral outlines, each, block of one series having one right-lined lateral surface, its ends of corre sponding formation and provided with a projection or extension and a recess, respectively, and its opposite lateral surf ace having a longitudinal recess; each block of the second series being of approximately right-angled formation, one arm of the angle having a recess facing at right angles to the extension or projection of tneother arm of the angle;
